Cracking does not occur in a ferroelectric thin film even when Ce is not doped in a composition for forming ferroelectric thin films and a composition for forming relatively thick ferroelectric thin films contains lead acetate instead of lead nitrate. A ferroelectric thin film made of a titanate lead-based perovskite film or a titanate zirconate lead-based complex perovskite film is formed using the composition for forming ferroelectric thin films. The composition includes lead acetate, a stabilizing agent made of lactic acid and polyvinyl pyrrolidone. In addition, a monomer-equivalent molar ratio of polyvinyl pyrrolidone to a perovskite A site atom included in the composition is more than 0 to less than 0.015. Furthermore, a weight average molecular weight of the polyvinyl pyrrolidone is 5000 to 100000.
